The qapi enum ErrorClass is unusual that it uses 'CamelCase' names, contrary to our documented convention of preferring 'lower-case'. However, this enum is entrenched in the API; we cannot change what strings QMP outputs. Meanwhile, we want to simplify how c_enum_const() is used to generate enum constants, by moving away from the heuristics of camel_to_upper() to a more straightforward c_name(N).upper() - but doing so will rename all of the ErrorClass constants and cause churn to all client files, where the new names are aesthetically less pleasing (ERROR_CLASS_DEVICENOTFOUND looks like we can't make up our minds on whether to break between words). So as always in computer science, solve the problem by some more indirection: rename the qapi type to QapiErrorClass, and add a new enum ErrorClass in error.h whose members are aliases of the qapi type, but with the spelling expected elsewhere in the tree. Then, when c_enum_const() changes the munging, we only have to adjust the one alias spot. Backports commit f22a28b898322c01b0463a8b7ec551d72bc61a5b from qemu
